Was having a discussion on another board the other day and the subject of tin and wheel weights came up. Back when Shooters.com was still up and we had the Cast Bullet Board to loaf around on, I was taught that care must be taken to properly flux when melting down WW and to stir well to ensure uniformity of the alloy. A big concern was to NOT skim the shiny metal that floated to the surface, along with the crud and steel clips, as that was the tin. Got a guy on the other board telling me I'm full of $hit, to use his words, "Once amalgamated, tin does not separate from the alloy and therefore you can't skim it off." Can anyone offer clarification on this?
